I heard about these folks while I was listening to Howard Stern. I decided to give them a try and was not disappointed. First of all, $9.99 for a haircut is always a value considering how some "salons" can gouge guys for haircuts (not all us go to barbers). They were fast and good, unlike one of their main competitors (national chain - you know who I'm talking about) they listen to you and help make you look good.
As far as wait times, I've never had to wait more then 10 minutes. Walk-ins are not just welcomed, they are encouraged. Strange, but true just stop by and they'll take care of you.
